Subject: [Qemu-devel] Performance Monitoring
Hi All,
I'm doing a research project in which i want to run an OS under an emulator
for a period of time and get full CPU opcode statistics (how many times
every opcode was executed). As far as i understand the Qemu design, it is
doing "JIT" translation of terget opcode to host opcodes to improve
performance, and so there is no easy way to count target opcodes (e.g a loop
is compiled JIT and runs natively).
Is it possible to disable Qemu's JIT capabilities and get target opcode
statistics?
